Cloud-based outsourced storage relieves the client's load of storage management and preservation by providing an equivalently flexible, inexpensive, location-independent platform. As clients no longer have physical control of data, outsourced data integrity checking is of crucial importance in cloud storage. It allows the clients to verify data intactness and correctness without downloading the entire data. As the verification is to be done at client end, the integrity checking protocol must be efficient to save client's time. Another aspect of the protocol is flexibility, which improves the quality of integrity checking by allowing user specific block partition size.
